Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an active liquid crystal device including a two-terminal switching element and an electronic apparatus.
[0002]
[Prior art]
A liquid crystal device is configured by sealing liquid crystal between two substrates such as a glass substrate and a quartz substrate. The structure of the liquid crystal device includes a passive type in which pixels are arranged in a matrix on the surface of a substrate, and a non-linear type such as a TFT (Thin Film Transistor) or a TFD (Thin Film Diode) for each pixel. An active element is provided in which an element is provided, and a signal electrode and a pixel electrode are connected via the non-linear element.
[0003]
In an active liquid crystal device, active elements are arranged in a matrix on one substrate, electrodes facing the other substrate are arranged, and the optical characteristics of a liquid crystal layer sealed between the two substrates are determined according to image signals. The image display is made possible by changing For example, an image signal is selectively supplied to pixel electrodes (ITO (Indium Tin Oxide)) arranged in a matrix by using a TFD element as a switching element, and an image signal is supplied to a liquid crystal layer between electrodes facing the pixel electrode. The applied voltage changes the arrangement of the liquid crystal molecules. Thus, the image display is performed by changing the transmittance of each pixel and changing the light passing through the pixel electrode and the liquid crystal layer according to the image signal.
[0004]
Note that in order to regulate the arrangement of liquid crystal molecules when no voltage is applied, the liquid crystal layers of one substrate (an active matrix substrate (hereinafter, also referred to as a first substrate)) and another substrate (hereinafter, also referred to as a second substrate) are used. An alignment film is formed on a surface in contact with the substrate, and a rubbing process is performed on the alignment film.
[0005]
Incidentally, an element having an MIM (Metal Insulator Metal) structure may be used as the TFD element. The MIM element has a stacked structure of a metal film, an insulating film, and a metal film, and is used as a switching element that controls supply of an image signal to a pixel by using its nonlinear characteristic.
[0006]
FIG. 7 is an explanatory diagram showing a configuration of an electrode of a liquid crystal device using such a TFD.
[0007]
On one substrate (first substrate) 50 side, pixel electrodes 51 using MIM elements as switching elements are formed in a matrix. On the other hand, on the other substrate (second substrate) 55, scanning electrodes 56 extending in the row direction are formed in a stripe shape.
[0008]
The MIM element of each pixel is turned on according to the drive voltage applied to the scanning electrode 56, and writes the image signal supplied via the signal electrode 57 to each pixel electrode 51. That is, the MIM element at a position facing the scanning electrode 56 to which the predetermined driving voltage is supplied is turned on, and the image signal from each signal electrode 57 is supplied to all the pixel electrodes 51 in one line.
[0009]
[Problems to be solved by the invention]
Incidentally, the MIM element is formed by a lower metal layer formed by extending the signal electrode, an insulating film layer formed on the lower metal layer, and an upper metal layer formed on the insulating film layer. In this configuration, the upper metal layer is connected to the pixel electrode.
[0010]
However, in the step of forming the insulating film layer on the lower metal layer, the insulating film layer is also formed on the signal electrode integrally formed with the lower metal layer. Further, a metal layer made of the same material as the upper metal layer constituting the MIM element is formed on the insulating film layer on the signal electrode.
[0011]
The signal electrode also has an MIM structure due to the insulating layer and the metal layer formed on the signal electrode.
[0012]
However, when a driving voltage for turning on the MIM switching element is applied to the scanning electrode at a position facing the signal electrode due to the MIM structure of the signal electrode, the liquid crystal moves between the signal electrode and the scanning electrode at the position facing the same. The sequence of the molecule is affected.
[0013]
FIG. 8 is an explanatory diagram for explaining this problem, and shows a cross-sectional structure viewed from the direction B in FIG.
[0014]
On the first substrate 50, a pixel electrode (shaded portion) 51 is formed. A scanning electrode 56 is formed on the second substrate 55 at a position directly above the pixel electrode 51. The arrangement of the liquid crystal molecules 59 is controlled between the pixel electrode 51 and the scanning electrode 56 according to an image signal.
[0015]
On the other hand, signal electrodes (reticles) 57 are also formed between the pixel electrodes 51. However, immediately above the signal electrode 57, there is a portion where the scanning electrode 56 is not formed. For this reason, the signal electrode 57 generates an electric field (hereinafter, referred to as a horizontal electric field) between the signal electrode 57 and the scanning electrode 56 adjacent to the position immediately above. The lateral electric field due to the leak current from the signal electrode 57 adversely affects the arrangement of the liquid crystal molecules 59 at the edge of the pixel electrode 51. That is, in the peripheral portion of the pixel electrode 51, poor alignment of the liquid crystal molecules 59 occurs, and the contrast ratio is reduced due to light leakage at the poorly aligned portion, and a blurred image is displayed.
[0016]
The present invention has been made in view of such a problem, and even when a leak current occurs from a signal electrode, it is possible to reduce a horizontal electric field to obtain a sufficient contrast ratio and improve image quality. It is an object of the present invention to provide a liquid crystal device and an electronic device that can be operated.
[0017]
[Means for Solving the Problems]
A liquid crystal device according to the present invention supplies a plurality of pixel electrodes formed on a first substrate and arranged in a matrix, and signals to the pixel electrodes of each column extending in a column direction on the first substrate. A plurality of stripe-shaped signal electrodes, a plurality of stripe-shaped scan electrodes extending in a row direction on a second substrate opposed to the first substrate, and opposed to the pixel electrodes in each row; And a metal film formed at least in a portion where the scanning electrode is not formed and in a portion facing the signal electrode.
[0018]
According to such a configuration, on the first substrate, a plurality of pixel electrodes arranged in a matrix and a striped signal extending in the column direction and supplying a signal to the pixel electrodes in each column are provided. An electrode is formed. On the other hand, on the second substrate, stripe-shaped scanning electrodes extending in the row direction and arranged to face the pixel electrodes in each row are formed. Further, a metal film is formed on at least a portion where the scanning electrode is not formed and a portion facing the signal electrode on the second substrate. As a result, the scanning electrode or the metal film always faces the signal electrode, and the leak current from the signal electrode travels toward the scanning electrode or the metal film facing the signal electrode. Therefore, a horizontal electric field is not generated by the leakage current, a high contrast ratio is obtained, and a clear high-quality image can be obtained.
[0019]
Further, the metal film is formed in a matrix along a portion where the scanning electrode is not formed and the signal electrode.
[0020]
Further, the metal film is formed in a stripe shape along a portion where the scan electrode is not formed.
[0021]
Further, the metal film is formed in a stripe shape along the signal electrode.
[0022]
According to these configurations, the scanning electrode or the metal film is always arranged opposite to the signal electrode, thereby reducing the generation of the lateral electric field due to the leak current, and providing a high-contrast ratio clear and high-quality image. Can be obtained.
[0023]
Further, the metal film is supplied with a predetermined fixed potential.
[0024]
According to such a configuration, the leak current from the signal electrode can be advanced to the metal film, and the generation of the lateral electric field can be reduced.
[0025]
Further, the metal film is formed along a light shielding film formed on the second substrate.
[0026]
According to such a configuration, the metal film can be formed in the same pattern as the light-shielding film formation pattern.
[0027]
An electronic apparatus according to the present invention includes the liquid crystal device as an image forming unit.
[0028]
According to such a configuration, since a horizontal electric field due to a leak current does not occur in the liquid crystal device, a clear high-quality image with a high contrast ratio can be obtained.
[0029]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a cross-sectional view illustrating a configuration of a liquid crystal device according to a first embodiment of the present invention, and FIG. 2 is an enlarged perspective view illustrating a main part of the liquid crystal device. A sectional view taken along line AA 'in FIG. 2 corresponds to FIG.
[0030]
In the first embodiment, the present invention is applied to an active matrix transmission type liquid crystal device. Hereinafter, a case where a TFD (Thin Film Diode) which is a two-terminal switching element is used as the switching element will be exemplified. In each of the drawings described below, the scale of each layer and each member is different so that each layer and each member have a size that can be recognized in the drawings.
[0031]
In the present embodiment, the metal film is formed at a position facing the signal electrode formed on the first substrate and at a position where the scanning electrode is not formed on the second substrate, so that the position facing the signal electrode is formed. In this configuration, a scanning electrode or a metal film is disposed so that a leakage current from a signal electrode flows in a direction in which no lateral electric field is generated.
[0032]
1 and 2, the liquid crystal device 1 has a configuration in which a first substrate 11 and a second substrate 12 facing each other are bonded together with a sealant 13 therebetween, and a liquid crystal 14 is sealed between the two substrates. ing. The first substrate 11 and the second substrate 12 are plate members having optical transparency, such as glass, quartz, and plastic. Note that, in actuality, a polarizing plate or a retardation plate for changing incident light is attached to the outer surface (the side opposite to the liquid crystal 14) of the first substrate 11 and the second substrate 12, Since there is no direct relationship with the contents of the present invention, illustration and description thereof are omitted.
[0033]
A plurality of pixel electrodes 111 arranged in a matrix are formed on the inner surface (the liquid crystal 14 side) of the first substrate 11, and the pixel electrodes 111 extend in the Y direction of the screen (the direction perpendicular to the paper surface of FIG. 1) in the gap between the pixel electrodes 111. And a plurality of existing signal electrodes 112 are formed. Each pixel electrode 111 is formed of, for example, a transparent conductive material such as ITO.
[0034]
Each pixel electrode 111 and a signal electrode 112 adjacent to the pixel electrode 111 are connected via a TFD 113 (not shown in FIG. 1). Each TFD 113 is a two-terminal switching element having a non-linear current-voltage characteristic, and has an MIM structure. The surface of the first substrate 11 on which the pixel electrode 111, the signal electrode 112, and the TFD 113 are formed is covered with an alignment film 114. The alignment film 114 is an organic thin film such as polyimide, and has been subjected to a rubbing process for defining the alignment direction of the liquid crystal 14 when no voltage is applied.
[0035]
On the other hand, a color filter 122 (122R, 122G and 122B), a light-shielding layer 123, a metal film 121, an overcoat layer 124, a plurality of scanning electrodes 125 and the alignment An alignment film 126 similar to the film 114 is formed. Each scanning electrode 125 is a strip-shaped electrode formed on the surface of the overcoat layer 124 by a transparent conductive material such as ITO. Each scanning electrode 125 extends in a direction intersecting with the above-mentioned signal electrode 112 (the left-right direction in FIG. 1), and is opposed to a plurality of pixel electrodes 111 forming a row on the first substrate 11.
[0036]
The color filters 122 (122R, 122G, and 122B) are layers formed of a resin material on the second substrate 12, and are formed of any one of R (red), G (green), and B (blue) by a dye or a pigment. Crab is colored. FIGS. 1 and 2 illustrate a case where a so-called stripe arrangement in which color filters 122 of the same color are arranged in pixels in the same column is employed.
[0037]
The light-shielding layer 123 is formed in a lattice shape so as to cover a gap portion between pixels arranged in a matrix, that is, a region other than a region where the pixel electrode 111 and the scanning electrode 125 face each other. It plays a role of improving the contrast of a displayed image by shielding light. Note that, for example, the light shielding layer 123 is formed of a resin material containing a black colorant such as carbon black or a pigment.
[0038]
Here, the light shielding layer 123 is formed on the surface of the color filter 122 after the color filter 122 is formed on the surface of the second substrate 12. Therefore, the light shielding layer 123 is located closer to the first substrate 11 than the color filter 122, as shown in FIGS.
[0039]
In the present embodiment, the metal film 121 (the hatched portion in FIG. 2) is formed on the light shielding layer 123. That is, the metal film 121 is formed in a lattice shape so as to cover a region other than a region where the pixel electrode 111 and the scanning electrode 125 face each other. That is, when viewed in a plan view, as shown in FIG. 2, on the second substrate 12 side, a metal material of the scan electrode 125 and the metal film 121 is formed on the entire surface.
[0040]
The signal electrode 112 on the first substrate 11 is formed in a stripe shape between the pixel electrodes 111, and since the metal film 121 is formed, the scanning electrode 125 or the metal film Either of 121 is always present. The metal film 121 is connected to a predetermined fixed potential point (not shown).
[0041]
The overcoat layer 124 is a layer formed of an acrylic resin, an epoxy resin, or the like. The overcoat layer 124 flattens the unevenness formed on the second substrate 12 by the color filter 122 and the light-shielding layer 123, and causes the organic material to seep out from the color filter 122 and the light-shielding layer 123 to deteriorate the liquid crystal 14. Playing a role in preventing
[0042]
The signal electrodes 112 arranged in the row direction transmit an image signal given to each pixel electrode 111 in each row. A driving voltage for turning on the TFD 113 is sequentially supplied to the scanning electrodes 125 of each line, and all the TFDs 113 of each line are turned on by this driving voltage. The image signal transmitted via the signal electrode 112 is written to the pixel electrode 111 via the TFD 113. In this manner, a voltage is applied between the pixel electrode 111 on the first substrate 11 and the scanning electrode 125 facing the pixel electrode 111, and the alignment state of the liquid crystal 14 sandwiched between the two electrodes changes according to the image signal. As a result, the light transmittance changes, and an image is displayed.
[0043]
Next, a method of manufacturing the liquid crystal device shown in FIGS. 1 and 2 will be described with reference to the process chart of FIG. 3A to 3H show the manufacturing method in the order of steps.
[0044]
First, one surface of the second substrate 12 such as a glass substrate is colored in red, green, or blue with a dye or a pigment in FIG. 3A (red in FIG. 3B). A resin material is applied and flattened to form a colored resin layer 32 (FIG. 3B). Note that an acrylic resin having photocurability is used as the resin material.
[0045]
Next, as shown in FIG. 3B, the colored resin layer 32 is covered with a mask 31 having an opening 31a in a region where a color filter 122 corresponding to the color of the colored resin layer 32 is to be formed. Then, the colored resin layer 32 is irradiated with ultraviolet rays through the mask 31. As a result, portions of the colored resin layer 32 that are not covered by the mask 31 are selectively irradiated with ultraviolet rays and cured. Thereafter, by developing the colored resin layer 32, a red color filter 122R is formed as shown in FIG. Next, the processing shown in FIGS. 3B and 3C is similarly performed for other colors (green and blue). Thus, as shown in FIG. 3D, color filters 122R, 122G, and 122B corresponding to the respective colors of R, G, and B are formed on the surface of the second substrate 12.
[0046]
Next, a resin material colored black with carbon black is applied and flattened on the surface of the second substrate 12 on which the color filter 122 is formed to form a black resin layer 33 (FIG. 3E). For example, an acrylic resin having photocurability is used as the resin material. Next, the black resin layer 33 is covered with a mask 34. In the mask 34, an opening 34a is formed corresponding to a region of the black resin layer 33 to be the light shielding layer 123.
[0047]
Next, as shown in FIG. 3E, the black resin layer 33 is irradiated with ultraviolet rays via a mask. As a result, a portion of the black resin layer 33 corresponding to the opening 34a of the mask 34 is selectively irradiated with ultraviolet rays and cured. Thereafter, the black resin layer 33 is developed to remove the portions not irradiated with ultraviolet rays, thereby forming a grid-like light-shielding layer corresponding to the gaps between the pixels as shown in FIG. 123 are formed.
[0048]
Next, in this embodiment, the metal film 121 is formed over the color filter 122 and the light-blocking layer 123. Then, a lattice-shaped metal film 121 is formed by photolithography and etching so as to overlap the light-shielding film 123 in a plan view (FIG. 3G).
[0049]
Next, an acrylic resin, an epoxy resin, or the like is applied so as to cover the color filter 122, the light-shielding layer 123, and the metal film 121 formed as described above, so that an overcoat layer 124 is formed. Next, as shown in FIG. 3H, a scan electrode 125 is formed on the surface of the overcoat layer 124 using ITO, and an alignment film 126 such as polyimide is formed, followed by rubbing.
[0050]
On the other hand, the pixel electrode 111, the signal electrode 112, and the TFD 113 are formed on the surface of the first substrate 11. These components can be formed by using various known methods, and a description thereof will be omitted. Next, a frame-shaped sealing material 13 surrounding the edge of the second substrate 12 is printed on the second substrate 12 obtained by the process of FIG. 3, and the second substrate 12, the pixel electrodes 111 and the like are formed. The bonded first substrate 11 is bonded via the sealing material 13. Thereafter, the liquid crystal 14 is sealed between the two substrates, and a polarizing plate or a retardation plate is attached to the outer surfaces of the two substrates, thereby obtaining the liquid crystal device 1 shown in FIGS.
[0051]
FIG. 4 is an explanatory diagram for explaining a leak current generated in the present embodiment. FIG. 4 shows the positional relationship among the pixel electrode 111, the signal electrode 112, the scanning electrode 125, and the metal film 121 when viewed from the direction C in FIG.
[0052]
On the first substrate 11, the signal electrodes 112 extend in the Y direction of the screen and do not extend in the scanning line direction. The signal electrodes 112 are formed over the entire area in the Y direction, and the pixel electrodes 111 are formed at predetermined intervals in each row. On the other hand, in the second substrate 12, the scanning electrodes 125 are formed on the pixel electrodes 111, and have a predetermined interval for each row. Therefore, the signal electrode 112 does not face the scanning electrode 125 in the gap between the scanning electrodes 125.
[0053]
In the present embodiment, the metal film 121 is formed on the second substrate 12 in the gap between the scan electrodes 125. Therefore, the scanning electrode 125 or the metal film 121 is arranged so as to face all the regions of the signal electrode 112.
[0054]
Therefore, as shown in FIG. 4, even in the gap between the scan electrodes 125, the leak current from the signal electrode 112 proceeds toward the metal film 121 that is disposed facing (arrow in FIG. 4). Therefore, the generation of the lateral electric field is also suppressed by the leak current generated by the signal electrode 112 having the MIM structure.
[0055]
As described above, in the present embodiment, the metal material is disposed in the gap between the scan electrodes by forming the metal film on the lattice-shaped light-shielding film formed on the second substrate. As a result, the metal material of the scanning electrode and the metal film is formed on the entire surface of the second substrate facing the signal electrode on the first substrate when viewed in a plan view, and the leakage current from the signal electrode is reduced. Since the light travels to the scanning electrode or the metal film that is disposed to face the surface, the generation of a lateral electric field can be suppressed. Thereby, it is possible to prevent the occurrence of poor alignment of the liquid crystal at the periphery of the pixel electrode, and it is possible to display a clear high-quality image by improving the contrast ratio.
[0056]
Note that, in the above embodiment, the metal film 121 is formed over the entire area of the lattice-shaped light-shielding film 123. However, as described above, the metal film is formed in the gap between the scan electrodes and What is necessary is just to form in the part opposing the signal electrode 112, ie, only in the gap part between four pixel electrodes adjacent up, down, left, and right.
[0057]
FIG. 5 shows an example in which the metal film 131 is formed only on the gap between the scan electrodes 125 in the grid-like light shielding film 123. The metal film 131 is connected to a predetermined fixed potential point. Also in the example of FIG. 5, the leak current from the signal electrode 112 proceeds only to the opposing scan electrode 125 or the metal film 131, and it is possible to prevent the generation of a lateral electric field.
[0058]
Further, in the example of FIG. 5, an example in which the stripe-shaped metal film 131 is continuously formed for one row has been described. However, if a fixed potential can be supplied to the metal film 131, the metal film 131 is divided and provided. You may. For example, it is clear that the line may be divided into two at the center in the row direction and connected to a fixed potential at both ends of the substrate.
[0059]
Further, it is obvious that the metal film may be formed only on the second substrate along the signal electrode 112 in the lattice-like light-shielding film 123. In this case, the metal film may be connected to a predetermined fixed potential point.
[0060]
Depending on the shape of the metal film formed on the light-shielding film, various methods are conceivable for applying the fixed potential. For example, in the metal films 121 shown in FIGS. 1 and 2, all the metal films 121 are commonly connected, and a common fixed potential is applied to the metal films 121 facing the signal electrodes at all positions on the screen. Have been. On the other hand, it is conceivable to switch the fixed potential of the metal film according to the position of the signal electrode. In this case, for example, the metal film may be formed in an electrically separated shape as in the example of FIG.
[0061]
Note that, in the above-described embodiment, a device which includes a color filter and can perform color display has been described. However, the present invention can be similarly applied to a liquid crystal device having no color filter. In addition, although an example in which the present invention is applied to a transmissive liquid crystal device has been described, it is apparent that the present invention is also applicable to a reflective liquid crystal device and a transflective liquid crystal device.
